DC-Transformer 257LE-24-SD

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 10 ... 35 VDC
  • very high efficiency: up to 98%
  • input surge voltage: 37 VDC
  • output voltage / max. output current: 24.0 VDC / 13.0 ADC


The L-version operates at very low input voltages from around 9VDC. This allows supercapacitor-supplied systems to be discharged very deeply. The converter with 24V output and up to 13A short-circuit current is ideally designed for stabilizing the 24V on-board power supply. Customer-specific DC-DC converters with the following output voltages are possible:


  • non-isolated step up and step down converter
  • very low input ripple and noise
  • continous no load and short circuit proof
  • for ambient temperatures of -40°C up to +85°C
  • thermal shutdown at +90°C
  • for active loads, can be connected in parallel
  • integrated EMI input and output filter
  • no derating of power
  • heatsinking metal case
  • robust design
  • unipolar output voltage
  • non-isolated output
